Clinical observation of Danzhi Xiaoyao Capsule with hypromellose 2910, dextran 70 and glycerol eye drops for dry eye in menopausal patients / 国际眼科杂志(Guoji Yanke Zazhi)

?AIM: To evaluate the clinical effects, corneal surface shape and corneal thickness variation after treated by Danzhi Xiaoyao Capsule combined with hypromellose 2910, dextran 70 and glycerol eye drops for dry eye in menopausal patients.?METHODS: Eighty menopausal patients ( 160 eyes ) diagnosed as dry eye were randomly divided into groups A and B ( 40 patients each ) . Group A was treated with hypromellose 2910,dextran 70 and glycerol eye drops only and group B was treated with Danzhi Xiaoyao Capsule and eye drops. Before and 1mo after treatment, the clinical effects were evaluated by symptom scores, fluorescein staining ( FL ) , tear film breakup time ( BUT ) and Schirmer Ⅰ test. While the corneal surface regularity index (SRI), surface asymmetry index (SAI) and central corneal thickness ( CCT) were observed.? RESULTS: At 1mo after treatment, the symptoms scores and FL scores of the 2 groups decreased significantly( P0. 05).?CONCLUSION: Combination therapy of Danzhi Xiaoyao Capsule and hypromellose 2910, dextran 70 and glycerol eye drops for menopausal patients with dry eye is more effective than single eye drops, and can improve the symptoms and signs.

Content Determination of Dextran70 in Compound Dextran70 Eye Drop by HPLC-RID / 中国药房

OBJECTIVE:To establish a method for determination of dextran70 in Compound dextran70 eye drop. METHODS:HPLC-RID was performed on the column of Phenomenex PolySep-GFC-P 4000 with the mobile phase of 0.7% Na2SO4 solution. The flow rate was 0.5 ml/min,column temperature was 35 ℃ and injection volume was 50 μl,and the inner temperature of refrac-tive index detector was 40 ℃. RESULTS:The linear range of dextran70 was 0.1-5.0 mg/ml(r=0.999 5);RSDs of precision,sta-bility and reproducibility tests were lower than 2%;average recovery was 97.45%-101.76%(RSD=0.57%,n=9). CONCLU-SIONS:The method is simple,fast and reliable with high separation and short analysis time,and can be used for the content deter-mination of dextran70 in Compound dextran70 eye drop.

Autologus normovolemic and hypervolemic hemodilution during surgery using 6% dextran 70 and lactated ringer solution: impact on mean arterial pressure, heart rate, hemoglobin and hematocrite (A preliminary study).

Autologous normovolemic hemodilution (ANH) is one of the methods to conserve blood donor (homologous). The decrease in hemoglobin (Hb) due to bleeding in major surgery will be minimized and the hematocrite (Hct) will be adjusted accordingly by this method. However, due to its impractical clinical application, another simpler hemodilution method is used, i.e. hypervolemic hemodilution (HHD), using 6% dextran 70 and lactated Ringer solutions. The aim of this randomized comparative study was to investigate the impacts of both hemodilution methods (ANH and HHD) on mean arterial pressure (MAP), heart rate (HR), hemoglobin (Hb) and hematocrite (Hct) in anesthetized patients undergoing major surgery. Fourteen (14) women fulfilling the inclusion and exclusion criteria were divided into 2 groups. Seven (7) women received ANH and seven (7) women received HHD method. There were significant statistical differences (P<0.05) between ANH and HHD groups in MAP and Hct after 1 minute (86.3±9.1 vs. 99.1±6.4 on MAP) and (27.3±1.7 vs. 31.5±4.4 on Hct) and after 20 minutes (87.7±7.3 vs. 98.3±6.8 on MAP) and (27.4± 1.7 vs. 3.6±4.8 on Hct) post-hemodilution respectively. There was no difference in HR and Hb. No statistical difference between the four parameters tested after 120 minutes post-hemodilution. It may be concluded that both methods worth to be used in clinical setting although further studies are required.
